David,

This is the response to your question from Mary Brady who is in charge of 
our XML Testing activities:

It's actually a mathematical term, because the majority of the
test assertions are written using if...then...(else) logic or a=>b
(a implies b). The if clause or the a part is typically referred
to as the premise. If you are not mathematically inclined, the
same ideas can be stated in other ways. Essentially, you are
trying to identify concrete behaviors, defined in the spec, that
can be easily testable.
